High voltage inverter for PMSM FGI high-voltage permanent magnet synchronous motor inverter, with high-speed DSP as the control core, adopts space voltage vector control technology, power unit series multi-level technology, with high reliability, easy operation and high performance as the design goals, to meet the needs of various users It is a high-voltage source type inverter to meet the needs of load speed regulation, energy saving and production process improvement. Precise and efficient control of high-voltage permanent magnet synchronous motors. When the synchronous motor is running, the angle δ (power angle) between the armature voltage vector and the rotor magnetic pole position must vary within the range of 0 to 90°, otherwise it will cause out of step. The high-voltage permanent magnet synchronous motor inverter provided by our company has the function of preventing out-of-step. The high-voltage permanent magnet synchronous motor inverter provided by our company is suitable for occasions with high control precision, large starting torque and large load changes.
